Tour Overview
4 days 3 nights private adventure journey through Tan Hoa - Tu Lan cave system - river & dry caves - underground river - Tan Hoa. The route is shaped around clear pacing, trusted local guidance and enough flexibility to adjust hotels, transfers and touring style before quote.
This 4 days 3 nights adventure into Phong Nha-Ke Bang — a UNESCO World Heritage site in Quang Binh, home to the planet's greatest caves — is operated by Oxalis Adventure, the licensed specialist for the Tu Lan and Son Doong cave systems. The route takes in Tu Lan Cave System, Underground rivers, Dry caves and Tan Hoa Village.
This is a join-in small-group expedition (join-in, max 10 guests) with professional guides, safety assistants and porters to international safety standards. Adventure level: Hard. Price: 18,000,000 VND (~$679) per person.
Oxalis Adventure holds the operating licence for these caves and runs every tour with cave experts trained by the British-Vietnam Cave Expedition team. Spread across 4 days 3 nights, the expedition includes wild jungle/cave camping with full logistics — meals, tents and safety gear all provided. Group size is capped for safety and conservation.
A demanding expedition for fit, experienced adventurers — trekking experience and a good fitness base are required (able to run 5 km and climb several flights without trouble). All equipment, safety briefing and trained staff are provided.
Cave tours run seasonally (most operate roughly January–August/September; some longer) and routes are weather dependent — paths can be muddy and slippery in rain and may be modified for safety. Bring trekking shoes, quick-dry clothing and swimwear. Booking is confirmed on full payment; a full refund applies if cancelled 7+ days before departure. From $679 per person, reconfirmed by date and availability at booking.

Genuinely one of the best travel days of my life
We did the cycling and cooking session as a couple celebrating our anniversary. The guide was warm, the pace was relaxed, and the farmhouse lunch felt completely authentic. Nothing felt staged.

The herbal session at the end was unexpected magic
I booked this mostly for the cycling but the herbal wellness close at the end completely surprised me. Sitting outside with the foot soak after the ride, looking out over the garden — it's the kind of moment you don't plan for.

Private and personal — felt nothing like a group tour
As a Vietnamese-Canadian I was a bit nervous this would feel touristy. It didn't at all. The family we cooked with was genuinely hospitable, the herbs were real, and the guide spoke about the village with obvious pride.

Seamless logistics, beautiful setting
The van pickup was on time, the bikes were in great condition, and every transition between activities felt smooth. My group of four had very different fitness levels and the guide adjusted the pace.

Worth every cent — and then some
I compared four different Hanoi day tours before booking this one. The itinerary description was the most honest and specific I found. What was promised is exactly what was delivered.

Took my parents — best decision of the trip
My parents are in their 60s and I wasn't sure about the cycling. Completely unnecessary worry — the lanes are flat and gentle and the guide made my mom feel completely at ease.
